Please contact me offlist/directly if you have implemented:
LDAP authentication, using Mac OSX 10.5 server with it's bundled Open Directory as the backend to authenticate users on Linux, OSX (10.4 and 10.5) desktops, and Windows XP SP3 desktops.
A client has a setup of heterogenous desktop setup and wants to implement Directory Services for the organization.
The composition is 80% Linux desktop + 2 Linux File servers (NFS+Samba), 7 OSX desktops and 5 Windows XP desktops).
The user's Unix (Linux/OSX) profile is portable to the respective platform via LDAP and Windows profile is portable through Samba. Samba+LDAP back end needs to be configured on 2 Linux file servers as well on the OSX server (for user's home dir).
